Value Lean To Mini Greenhouses

Our Value Lean to Mini greenhouses are great for bringing on seedlings in the Spring and for Summer crops such as Tomatoes. They also make a fantastic place to over-winter more tender plants, as lean to models benefit from the ‘storage heater’ effect of the wall.

Manufactured in the UK from aluminium and glazed in 3mm toughened safety glass.

What is a Value Lean to Mini greenhouse?

A Value Lean to Mini greenhouse is designed to help extend the growing season, providing the maximum growing space for your money. Designed for more cost conscious gardeners, the Value Growhouse uses 3mm toughened safety glass and have less accessories included as standard compared to our Classic Growhouses (link).

The controlled environment of a Value Growhouse provides protection from cold weather, and the glass traps the warmth of the early spring sunshine, producing earlier crops. The wall will act like a storage heater, warming up in the daytime and releasing the heat in the evening, providing greater frost protection.

Benefits of a Value Growhouse

There are many benefits of our Value Lean to Mini greenhouses that are designed to extend the growing season in the Spring and the Autumn and make your gardening more productive than ever before.

  • With an extended growing season you can start planting earlier in the season and continue growing later into autumn or even winter.
  • Protect your seedlings and tender plants from pests as well as from harsh weather conditions such as heavy rain, strong winds and snow.
  • By controlling the temperature and humidity within the Mini greenhouse, you can create the ideal growing conditions for your plants.
  • As our aluminium Lean to Mini greenhouses are lean to models, they are less expensive than constructing a full greenhouse, as there is no back. However, they do need to be fixed back.
  • They can be fixed to either a wall or a sturdy fence, but a brick or stone wall has the advantage that it will retain the daytime heat, making it warmer than a freestanding greenhouse. If the Mini greenhouse is heated, heating costs will be lower.
  • A wide variety of plants can be cultivated or over-wintered in a Value Mini greenhouse, with faster, healthier growth and a potentially larger harvest.

How to use a Value Lean to Mini greenhouse

Here are a few tips to help you maximise the benefits of your Lean to Value Mini greenhouse.

Choose the right location

With a lean to Mini greenhouse, you are more limited with the location as you need a suitable wall or fence. The location needs plenty of ambient light, ideally with some direct sunlight for part of the day. Make sure the ground is firm and level – paving slabs are ideal.

Make sure the wall is relatively smooth, otherwise build a ‘goal post’ timber frame to screw the framework to. This can be sealed to the wall to provide a smooth vertical surface. Alternatively purchase a glass back.

If a fence is being used, make sure it is sturdy and does not move in the wind. It should be relatively draught free.

Prepare the ground

Level slabs are ideal. Well compacted gravel can be used although a small paving slab under each front vertical leg would provide a suitable ground fixing. If you plan to plant directly in the ground within the Mini greenhouse, make sure the soil is well-drained, preferably with the addition of compost or other organic matter. In this case, make sure slabs have been laid at the front edge of the Mini greenhouse.

Ventilate properly

It’s important to provide adequate ventilation within the Mini greenhouse to prevent overheating and excess humidity. In addition to opening the sliding doors, in hot weather, the roof panels can be removed. Shade covers are also available.

Water regularly

Plants grown in a Mini greenhouse may require more frequent watering than those grown outdoors, as the controlled environment can lead to faster evaporation. So monitor moisture levels to prevent dry soil.
As a rule of thumb, you should give your plants a quick drink to start with, then let that water soak in before watering again more extensively. Ideally all watering should be done first thing in the morning, to avoid losing moisture through evaporation throughout the day. During the summer months, you may also want to water in the evening so that the soil can soak overnight.

Control pests

While a Value Mini greenhouse can provide a barrier for pests and diseases, it’s still important to monitor them regularly and take preventative measures as needed.

Harvest regularly

Don’t forget to harvest your plants regularly to encourage continued growth and prevent overcrowding within your Value Mini greenhouse. This is especially important for fast-growing crops like tomatoes or cucumbers.

What to Grow in a Value Mini greenhouse

The versatile environment of a Value Lean to Mini greenhouse allows you to grow a wide variety of plants throughout the year.

Salad crops can be grown for most of the year in the UK. Vegetables, such  tomatoes, cucumbers and peppers grow particularly well in a Mini greenhouse. As do herbs which prefer warm temperatures such as basil, coriander, parsley, thyme and rosemary.

Depending on the size of your Value Mini greenhouse,  oranges, lemons and potted figs can also be grown. The protective environment of a Value Mini greenhouse is also ideal for over-wintering geraniums and fuchsias.

Frequently Asked Questions

  • What are your Lean to Mini greenhouses made of?

    Our framework of our Value Mini greenhouses are constructed in the UK from architectural-grade aluminium that comes with a 25-year guarantee.

    The Value Mini greenhouses are glazed in 3mm toughened safety glass – this is the same thickness as traditional horticultural glass, but the toughening process makes it about 7x stronger. If it breaks, for safety, it shatters into tiny pieces rather like a car window.

  • Is a Mini greenhouse the same as a greenhouse?

    Usually, Mini greenhouses are just smaller versions of regular greenhouses. So Mini greenhouses, obviously, take up less space. The built-in shelving system makes this space as versatile as possible. The same plants can be grown in both, but with a Mini greenhouse you would choose more compact varieties.

  • What’s the difference between your Classic and Value Mini greenhouses?

    Our Value lean to Mini greenhouses have been introduced to provide a good quality frame at a competitive price. Although built to the same exacting standards as our classic garden Growhouses, Value models do not have the additional extras.

    Our Value Growhouses still have toughened safety glass, but it’s standard 3mm horticultural thickness, rather than the 4mm of the Classic range. The sliding door handles are shorter on the Value range and they do not have corner trims to secure the doors and prevent draughts when the doors are closed.

    The Value Range does not have a watering system, or staging on the taller models – although these can be added as optional extras.

    The shelves use round bars and there are fewer bars per shelf, making the Value shelves ideal for plug plants and bringing on seedlings, but less suitable for heavy pots.

  • What is the easiest thing to grow in a Mini greenhouse?

    If you are new to gardening, it is much easier to grow with a Mini greenhouse that without one, so if you have tired gardening and have had good results, you will be even better with the protection of a lean to Mini greenhouse.

    A good starter for new gardeners are salad crops, as they are quick and easy to grow – especially plants such as radishes.

    Particularly well-suited to greenhouse growing in spring and summer are tomatoes, peppers and aubergines, which will thrive in the warmth. Courgettes, cucumbers and squashes also work well.

    If you’re looking to extend your growing seasons beyond summer, and even into winter, hardy plants which need a cooler temperature can easily be cultivated in a Growhouse. So carrots, onions, kale, cabbage and broccoli will all be ideal.

  • Do I need planning permission for Mini greenhouses?

    Due to their small size, and the fact that they can be classed as a temporary structure, it is highly unlikely that your garden Mini greenhouse will require planning permission.

    However, as regulations differ from council to council, you may want to contact your local authority for full clarification.

  • Why don't you glaze your Mini greenhouse in plastic

    Although plastics and acrylic glazing have come a long way, they are still not as good as glass in terms of light transmission and scratch resistance.

    Glass also traps heat from the sun – the greenhouse effect, better than plastic. This is especially noticeable early in the season when the sun is week.

    Glass is also heavy and rigid, giving the mini greenhouse excellent wind resistance in stormy conditions. Plastic sheets will flex in the wind and blow out of the frame more easily.

    The toughening process makes the glass sheets stronger and safer, ensuring there are no large shards if the glass is broken.
